    Description / Table of Contents: Résumé Chez 106 cadavres de japonais adultes, nous avons mis en évidence, aussi bien macroscopiquement que microscopiquement, des vaisseaux lymphatiques péri-oesophagiens qui se drainaient dans le conduit thoracique. Macroscopiquement, le drainage lymphatique de l'oesophage dans le conduit thoracique existait chez 46 des 106 cadavres (43,4 %). 23 gros collecteurs ont été vus qui naissaient de l'oesophage thoracique et s'abouchaient directement dans le conduit thoracique chez 21 des 106 cadavres (19,8 %). Le plus souvent (15 des 23 gros collecteurs), ces lymphatiques reliaient l'oesophage au conduit thoracique au niveau des 1er-3ème ou des 6ème-8ème vertèbres thoraciques. D'après l'examen histologique de ces 23 gros collecteurs, 2 prenaient naissance à partir d'un fin plexus lymphatique de l'adventice de l'oesophage infiltré de cellules mononucléaires. Dans 11 cas sur 23, un lymphonoeud intermédiaire a été trouvé sur le conduit thoracique grâce à des “clearing methods”. Ces résultats suggèrent que la lymphe de l'oesophage se draine rapidement dans la circulation systémique par l'intermédiaire du conduit thoracique. Importantes en clinique dans le cancer de l'oesophage, les descriptions antérieures de lymphatiques extrapariétaux de l'oesophage ont été discutées à propos de ce drainage lymphatique direct de l'oesophage.
    Notes: Summary The lymphatic vessels from around the esophagus which drain into the thoracic duct were identified macroscopically and histologically in 106 cadavers. Direct lymphatic drainage to the duct was macroscopically demonstrated by 84 vessels in 46 cases (43.4%). In 23 cases (19.8%), large collecting vessels arose from the thoracic esophagus and opened directly imto the duct. In most of these cases (15/23) these lymphatic connections were found at the levels of the 1st–3rd or 6th–8th thoracic vertebrae. Histologic study revealed that two vessels originated from the fine lymphatic plexus in the esophageal adventita, which showed monocytic infiltration. In 11 of the 23 cases, an intercalated node was found along the thoracic duct. The results suggest that lymph drains rapidly into the systemic circulation via the thoracic duct. In view of the clinical applications in esophageal carcinoma, previous accounts of the extramural esophageal lymphatics concerned in direct drainage are discussed.

    Increased lymphoid MxA expression in acute asthma exacerbation in children (2001)
    Copenhagen : Munksgaard International Publishers
    Allergy 56 (2001), S. 0

    Notes: Background: Although the association between acute asthma exacerbation and viral infection has been well documented, virus identification rates vary. It has recently been reported that the expression of MxA protein in lymphocytes, inducible by type I interferons, can serve as a sensitive marker for viral infection in the host. The objective was to determine the contribution of viral infection to precipitation of asthma attacks in children. Methods: We studied 186 asthmatic children, aged 0–12 years, over a 1-year period to evaluate MxA protein levels in peripheral blood lymphocytes by using a flow cytometric analysis in whole blood. Results: Of all the subjects, 80 (47%) exhibited significantly elevated levels of MxA expression in lymphocytes, presumably indicating the states of viral infection. The association of viral infections with acute asthma exacerbation seemed to be marked in younger children: enhanced MxA expression was seen in 73.3% of infants (aged 0–1 year), 49.5% of toddlers (aged 2–5 years), and 26% of schoolchildren (aged 6–12 years). Seasonal changes in the frequency of viral infection associated with deterioration were also observed. Conclusions: Flow cytometric assay of MxA protein expression in whole blood appears to be an easy and useful method to evaluate viral infections in acute asthma exacerbation.

    Studies of bronchial asthma induced by chironomid midges (Diptera) around a hypereutrophic lake in Japan (1997)

    Notes: There have been few reports on hypersensitivity to chironomid midges in bronchial asthmatic patients around the area of hypereutrophic natural lakes, which have been notorious as an environmental hazard due to the massive occurrence of adult chironomids during several periods of the year. Our study investigated IgE antibodies to chironomid midges in bronchial asthmatic patients around the Lake Suwa area in comparison with those of the Matsumoto area (control area). A total of 123 adult patients with bronchial asthma were investigated by measurement of IgE antibodies with extracts of three chironomid midges (Chironomus yoshimatsui, C. plumosus, and Tokunagayusurika akamusi), mite, and silkworm. In addition, in the allergy testing, 12 common inhalant antigens were used. Of 123 adult patients with bronchial asthma, 65 (52.8%) produced positive allergy tests. Thirty-three (50.8%) were positive to mite, 28 (43.1%) to silkworm, 11 (16.9%) to C. yoshimatsui, eight (12.3%) to C. plumosus, and three (4.6%) to T. akamusi. We compared our results with the previous reports. The number of positive tests to silkworm in the Lake Suwa area was higher than in other areas. However, C. plumosus and T. akamusi showed a lower number of positive reactions. We considered the lower positive number of C. plumosus and T. akamusi tests in the Lake Suwa area to be related to the advanced age of patients in this area. The chironomids are an important cause of asthma, together with mite and silkworm, in the Lake Suwa area, but affect old asthmatic patients less than asthmatic children.

    Vascular anatomy of the pancreaticoduodenal region: A review (1999)
    Springer

    Notes: Abstract: Vascular anatomy of the pancreaticoduodenal region has been the subject of numerous studies. However, several essential areas of confusion remain in interpretation of the vascular configuration. We note and discuss three key points in relation to this confusion: (1) a missing vascular arcade, (2) a rearrangement of the arcade by collateral and/or transverse vessels, and (3) a solitary vessel without an accompanying comites vein or artery. In addition, we consider that different interpretations as well as varying reported incidences depend on different "thresholds" when observations are made. Consideration of new aspects of vascular anatomy of the pancreaticoduodenal region is required for further improvement of surgical procedures. In terms of the selection of lymph node resection procedure, we discuss mainly the inferior arterial origin. Special attention should be paid to the ligation of inferior arteries because of the high incidence of the common trunk formation of the upper jejunal and inferior pancreaticoduodenal arteries. With regard to duodenum-preserving pancreatic head resection for benign tumors, our observations are introduced in view of either arterial or venous configuration. First, a communicating artery between the anterior and posterior arterial arcades is noted because of its possible critical role in blood supply to the papilla of Vater. Second, a venous drainage route from the duodenum to the retroperitoneal space in "normal" specimens is described.
